Thank you, Ken Jin! Very clear explanation!

> It seems the current consensus is to use that import for code with purely static typing, and not use it with runtime typing libraries.

Is it an official position? Or just a common usage pattern?
What can we do to make this more widely known?

Maybe we can formulate something like "When to use: raw, string, future annotations" in the typing docs (https://docs.python.org/3/library/typing.html)?
